110 all whom it may concern: Be it known that we, CLARENCE B: HAVEN and HARRY VANDERPOOL, citizens of the United States, residing at Niagara Falls,

county of Niagara, State of New York, and Turtle ,Creek, in the county of Allegheny and State of Pennsylvania, respectively, have invented certain new and useful Improvements in Gas-Heated Sad-Irons, of which the following is a specification.

Ofir invention consists of an improvement in sad irons and refers particularly to means for continuously heating an iron in the interior by the combustion of gaseous fuel, to heat radiating elements for such. purpose, incorporated with the iron, and to different features of construction as shall be more fully hereinafter set forth.

In the drawings: Figure 1 is a view of the-device in side elevation. Fig. 2 isa cross section on the line- II. II. of Fig. 1. Fig. 3 is a central longitudinal vertical view of the device. Fig. 4 is a plan. view of the iron showing the interior construction with the cover removed. Fig. 5 is a longitudinal sectional detail view of the burner. Fig. 6 is a View of the inner end of the burner.

ing an open interior 3, which is covered by a top 4 adapted to fit upon the upper edge 5 of the main body 2fandto be secured thereon by securin 7 devices as screws 6, 6. ownwardly through the top 4 at each side of the middle portionhnd are tapped into the base of the iron, which is preferably provided with receiving lugs 7. The top 4 is provided along each side with ample circulation apertures 8 for es 1 cape of the gases. of combustion, heated air,

etc. and is provided with a handle 9 secured to the top by connecting uprights 10, 10, fastened to the to 4 by screws 11. A shield 12 of asbestos, oard' or other suitable material on the upper side and a lower stiffening iece 13 of thin sheet metal, shieldstheban of the operator from the heat of the iron, such shield being connedted with the handle by screws 14, 14. We preferably alsoprovide heat insulating washers 15 of of the bottom of the main body 2 of the iron are a series of closely adjacentphis 16' which may be made of short A sections of V the sides. The body 2 ofthe iron is hollow, provid- --coxnplished by spinning of the metal. this construction the outer terminal of the heavy wire, and which are cast in the base of the 11011 in the operation of'making it from east metal. The'pins 16 are grouped in the forward interior portion of the hollow iron body, in the path of the circulation of the gases of combustionjrom theburner 17. Laid over the front end of said burner and covering the rearmost of said pins and extending to within a sufficient distance of the front of the iron to insure forward, upward and backward circulation of the gases, is a cover plate or shield 18 of thin sheet metal, held'in position by gravity and two screws, 6, 6] Said shield 18 is preferably turned downwardly at each side, as indicated at 19, whereby to fit snugly around and over the tops of the heat ab-- sorbing pins 16. The side edges 19 of the,

cover plate 18 are preferably spaced away from the inner sides of the main iron body 2, and rest lightly on the tops of pins 16,

being held against lateral movement by the screws 6. Bythis arrangement the heat of the flame passes under shield 18 and is always deflected downwardly to the bottom of the iron and prevented from passing to The burner 17 is composed of an inner tube 20, the rear end of which is screw threaded, as indicated at 21, and an outer tube 22 ofsomewhat enlar ed diameter. The front'portion of-tube 20 is enlarged to practically the-same diameter as the outer tube 22, or slightly less for interfitting engagement therewith, whereby to provide a mixing chamber 23 of enlarged diameter in the front portion of the tube. struction is effected by spinning the metal of tube 20, providing the smaller and larger diameters at each side of the intervening annular-1y crimped shoulder 24. The tubes 20 and 22, as thus made, are fixedly connected-together by an annular groove 25 acenlarged chambered portion 23 of the inner 'tube is provided Wlth' a shoulder immediately back of its end, for engagementby the inner terminal edges, by a cap 26 having an. inwardly extending annular flange Such contoo 27. The purpose of such flange is to retain ening series of spirally wound wires 31.

The air mixer is provided, as is usual in such devices, with a gas controlling valve 32 in the hose nipple and is so arranged that, by rotation of its rear portion, the supply of air to its interior through openings 33 may be readily regulated.

The rear portion of the burner 17 is provided with an annular groove 34 formed by depressing the thin sheet metal, and

when the burner is inserted in position through a suitable receiving opening 35 in' the rear upper portion of the iron body, it is secured in place by a set screw 36. Said set screwis mounted in a threaded opening in the rear portion 37 of the iron cover or top 4, and projects downwardly into the annular groove 34 of the burner. By this construction it will be seen that the burner is readily inserted through the opening 35 and will be fixedly held in position by the screw 36, and may be as readily andeasily taken out by loosening said screw. Also that the cap 26 of the burner may be as easily and quickly slipped offof the inner end of the burner for removal of a worn out or burnt out gauze disk 28 and renewal thereof. The iron is thus rendered very easily repaired by any one usin it, without the necessity :o-f any special ski l or tools. a The arrangement of the heat absorbing pins 16 and their manner of incorporation with the body of the iron render them very strong, serviceable and durable, and not easily .broken or damaged. The use of they pins, as thus arranged, and as composed of sections of steel wire, greatly assists n the distribution of the heat from the interior to the bottom or operative portion of the iron. .The entire hollow iron body is completely closed at its sides andend so that no heat or fianie can escape laterally to injure the goods, while the main effect of the heating gases is directed toward and absorbed by -the base portion, where it is most eflicient in the use of the iron. The shield 18 effects the proper circulation of the gases of combustion around and against the pins back- \vardly and upwardly to the escape openings 8.

The bottom surface, the outer surface of top 4 and lower side edges and front of the iron are preferably nickel-plated, giving the iron a highly ornamental appearance, and

and a securing set screw, of a burner consisting of a tubular shell having a maximum diameter corresponding to the width'of the burner opening and provided with an annulargroove near its front end, an endmost disk of wire gauze, a securing cap therefor having an outermost inwardly turned retaining flange for the gauze and an inwardly deflected rear portion for spring engagement with said annular groove, and a similar annular groove pressed around its rear portion adapted to be engaged by the set screw, substantially as set forth.

2. A burner for sadirons consisting of an inner tube having an annular groove near its end, an annularly crimped shoulder beyond said groove and a reduced fuel channel tubular portion having a threaded terminal,

an outer cylindrical shell surrounding said inner tube and fixedly connected therewith between said annular groove and threaded terminal and itself having an annular groove adjacent to said terminal, a disk of wire gauze laid over the end of the inner tube, and a securing cap therefor embracing the disk and the end of the innertube, substantially as set forth.

3. A burner for sadirons consisting of an inner tube having an annular groove near its end, an annularly crimped shoulder beyond said groove and a reduced fuel channel tubular portion having a threaded terminal, an outer cylindrical shell surrounding said inner tube and fixedly connected therewith between said annular groove and threaded terminal and itself having an annular groove adjacent to said terminal, a disk of wire gauze laid over the end of the inner tube, and a securing cap therefor embracing the disk and the end of the inner tube and having an inwardly deflected portion adapted to make spring engagement with the first named annular groove, sub,- stant-ially as set forth.

In testimony whereof we hereunto aflix our signatures in the presence of two witnesses.
